Abstract:
In order to make correct assessment of Guantouba bridge structure's health and safety condition, and to reflect the feature information of the structure state, the bridge vibration monitor system was designed. According to the risk analysis results of the bridge structure, seven monitoring sections were determined and fourteen three-axis acceleration sensors were arranged. The data acquisition and transmission module was designed which consisted of 12 bits A/D chip, 89C52, RS232 and DS1216 etc. It only needed 5 milliseconds to complete one data acquiring procedure. The data acquisition and analysis system could analyze and evaluate the monitoring data to make decisions for the bridge maintenance and management.The results show that the system can carry out the task of the bridge structure realtime monitoring and evaluating. It will trigger warning signal when the bridge is in special climate or dangerous traffic conditions. This system can provide basis for making decisions about the bridge operation, management and maintenance. It plays a very important role in ensuring the traffic safety on the bridge and the bridge operation security. 1 tab, 3 figs, 11 refs.
